Description

Technical Field

[0001] The utility model relates to the technical field of die-cutting machines, in particular to continuous die-cutting equipment for producing conductive foam. Background Art

[0002] Conductive foam refers to a flame-retardant sponge wrapped with conductive cloth. After a series of treatments, it has good surface conductivity and can be easily fixed on the device to be shielded with adhesive tape. Conductive foam also has sealing and shock resistance. It is usually fixed on electronic components to solve the problem of electromagnetic wave interference between electronic components. The raw material of conductive foam is a long strip material. It needs to be die-cut by a die-cutting machine to cut the conductive foam into small pieces of long strip materials for use.

[0003] However, after the existing die-cutting machine die-cuts the conductive foam, it can be transported to the cutting component through the conveying component for segmentation. The conductive foam is prone to deviation during the conveying process. When it is subsequently cut by the cutting component, the cut surface of the end of the conductive foam is prone to unevenness, which leads to poor segmentation effect of the conductive foam.

DETAILED DESCRIPTION

[0028] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined purpose of the utility model, the specific implementation method, structure, characteristics and effects of the present invention are described in detail below in combination with the accompanying drawings and preferred embodiments. Example

[0029] In order to improve the processing effect of foam cutting, a continuous die-cutting equipment for conductive foam production is designed. The specific scheme is as follows:

[0030] like Figure 1-7 As shown, a continuous die-cutting device for producing conductive foam includes a frame 1, on which a guide mechanism 2 and a limit mechanism 3 are fixedly installed, the limit mechanism 3 includes a support seat 301 and a clamping plate 302, two clamping plates 302 are fixedly installed on the frame 1, the clamping plate 302 is fixedly connected to the support seat 301, the support seat 301 is provided with a clamping groove 303, a hydraulic rod 304 is fixedly installed at the clamping groove 303, the telescopic end of the hydraulic rod 304 is fixedly connected to a clamping block 307, a fixed plate 305 is fixedly installed on the clamping block 307, a plurality of guide wheels 306 are rotatably connected to the fixed plate 305, and a cutting mechanism 4 is fixedly installed on the frame 1.

[0031] Specifically, the two clamping plates 302 are symmetrically arranged, and the hydraulic rod 304 is fixedly connected to the support base 301 . The support base 301 can be fixed on the frame 1 through the clamping plates 302 , thereby facilitating the installation and disassembly of the support base 301 .

[0032] Specifically, the block 307 is slidably connected to the support seat 301 , and the cross-sectional height of the block 307 is greater than the cross-sectional height of the slot 303 . When the block 307 slides in the slot 303 , the block 307 can drive the fixing plate 305 to move.

[0033] Specifically, the two fixed plates 305 slide towards each other, and a plurality of guide wheels 306 are arranged at equal distances. When the fixed plates 305 drive the guide wheels 306 to slide, the two groups of guide wheels 306 can contact the side wall of the conductive foam.

[0034] Specifically, the guide mechanism 2 includes a mounting frame 201 and a rotating block 203. Two mounting frames 201 are fixedly connected to the frame 1. A slide groove 205 is provided on the mounting frame 201. A rotating block 203 is rotatably connected to one mounting frame 201. A screw rod 208 is fixedly installed on the rotating block 203. A clamping rod 204 is threadedly connected to the screw rod 208. A guide roller 202 is rotatably connected to the clamping rod 204. A slide rod 206 is fixedly connected to the other mounting frame 201. A fixed rod 207 is fixedly connected to the two mounting frames 201. The clamping rod 204 and the fixed rod 207 are both rotatably connected to the guide roller 202. The rotating block 203 drives the screw rod 208 to rotate, and then the screw rod 208 drives the clamping rod 204 to slide inside the mounting frame 201.

[0035] Specifically, the slide groove 205 is slidably connected with a clamping rod 204, and the cross-sectional diameters at both ends of the clamping rod 204 are larger than the width of the slide groove 205. When the clamping rod 204 slides inside the mounting frame 201, it can drive a guide roller 202 to move, thereby facilitating the adjustment of the distance between the two guide rollers 202.

[0036] Specifically, the screw rod 208 is rotationally connected to the mounting bracket 201 , and the end of the clamping rod 204 away from the screw rod 208 is slidingly connected to the slide rod 206 . When the screw rod 208 drives the clamping rod 204 to slide, the end of the clamping rod 204 away from the screw rod 208 can slide along the slide rod 206 .

[0037] Specifically, the two mounting frames 201 and the slide groove 205 are symmetrically arranged, the clamping rod 204 is slidingly connected to the mounting frame 201, and the slide groove 205 limits the clamping rod 204, so that the clamping rod 204 drives the guide roller 202 to move, thereby facilitating the adjustment of the height of the guide roller 202 rotating on the clamping rod 204.

[0038] Specifically, the cutting mechanism 4 includes a slide plate 401 and a base 403. The base 403 is fixedly installed on the frame 1, the slide plate 401 is slidably connected to the base 403, the blade 402 is fixedly installed on the slide plate 401, the base 403 is fixedly connected to a material guide plate 404, and the baffle 405 is fixedly installed on the material guide plate 404. When the slide plate 401 slides into the base 403, the blade 402 can cut the conductive foam.

[0039] Specifically, the guide plate 404 is arranged in an inclined structure, and the two baffles 405 are symmetrically arranged on both sides of the guide plate 404 , and the cut conductive foam falls onto the guide plate 404 , and then the cut conductive foam can be collected by the guide plate 404 .

[0040] In the die-cutting equipment of this scheme, the conductive foam is transmitted to the top of the support seat fixed on the card plate through the guide mechanism. After the hydraulic rod is opened, the card block fixed at its telescopic end is displaced in the card slot provided in the support seat. The card block is limited by the card slot and can drive the fixed plate installed on the top to slide. A number of guide wheels are equidistantly connected in rotation in the fixed plate. When the two fixed plates slide toward each other on the support seat, the two sets of guide wheels can contact the side walls of the conductive foam, ensuring that the position of the conductive foam is limited during the transmission process, which is beneficial to prevent the conductive foam from running off and causing uneven subsequent cutting surfaces.

[0041] Working principle:

[0042] First, when the conductive foam after die-cutting is conveyed, the rotating block 203 can be rotated by hand, and the rotating block 203 drives the screw rod 208 to rotate in a mounting frame 201 fixed on the frame 1, and the screw rod 208 is threadedly connected with a clamping rod 204, and the clamping rod 204 is limited by a slide groove 205 provided in the mounting frame 201, so that the clamping rod 204 slides along the slide rod 206 fixed in another mounting frame 201, and the clamping rod 204 is rotatably connected with a guide roller 202, and the guide roller 202 is displaced when the clamping rod 204 slides, so that the conductive foam is in the middle of the two guide rollers 202, and the conductive foam contacts the side wall of the guide roller 202 during the conveying process, so that the two guide rollers 202 rotate along the clamping rod 204 and the fixed rod 207, so as to facilitate the guiding of the conductive foam;

[0043] The conductive foam is transferred to the top of the support seat 301 fixed on the card plate 302 through the guide roller 202. The control switch of the hydraulic rod 304 is turned on, which can drive the card block 307 fixed at the telescopic end to move in the card slot 303 provided in the support seat 301. The card block 307 is limited by the card slot 303, and can drive the fixed plate 305 installed on the top to slide. A number of guide wheels 306 are equidistantly connected to the fixed plate 305 for rotation. When the two fixed plates 305 slide toward each other on the support seat 301, the two groups of guide wheels 306 can contact the side wall of the conductive foam, thereby limiting its position during the transmission process of the conductive foam, which is conducive to preventing the conductive foam from running off and causing uneven subsequent cutting surfaces.

[0044] The conductive foam after limiting is transferred to the inside of the slide plate 401. Starting the slide plate 401 can drive the blade 402 to slide towards the base 403. When the blade 402 contacts the top of the conductive foam, the conductive foam can be cut. The cut conductive foam falls onto the guide plate 404. The guide plate 404 collects the cut conductive foam, and baffles 405 are fixed on both sides of the guide plate 404. The setting of the baffle 405 can prevent the collected conductive foam from falling from the guide plate 404.

[0045] The above are only preferred embodiments of the present invention, and are not intended to limit the present invention in any form. Although the present invention has been disclosed as a preferred embodiment as above, it is not intended to limit the present invention. Any technical personnel in this field can make some changes or modify the technical contents disclosed above into equivalent embodiments without departing from the scope of the technical solution of the present invention. However, any brief modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention are still within the scope of the technical solution of the present invention.
